(57) An electoerosion recording medium for generation of direct negatives or direct masters comprises a conventional support on which is deposited a thin conductive layer, and a protective overlayer comprising a crosslinked binder. The overlayer contains a solid conductive lubricant and optiona!- ly a particulate scouring agent to inhibit electrode fouling during writing. Preferably a hard base layer is present between the support and the conductive layer.
The specification describes a method of making a direct negative or direct offset by an electroerosion process using the foregoing recording medium, said method comprising selectively electro-eroding the conductive layer and thereby selectively simultaneously removing the crosslinked polymer layer.
